FRP

• Notes I have collected after February:

http://elm-lang.org/
  Elm is a functional language that compiles to HTML, CSS, and JavaScript.
  Designed for functional reactive programming, Elm makes it easy to create
  highly interactive applications.
    Elm’s Time Traveling Debugger
    Pause, rewind, and replay programs. Debug by changing history.
    http://debug.elm-lang.org/

React

Reading Group resources from Brandon Tilley:
  Overview/Brain Dump
    Templates vs. Components
    Coupling and Cohesion
    JSX—nice but not required
    “Just don’t write spaghetti code”—okay, what should we write?
    Passing props
    Evented architectures
    Flux
    Re-render the world
    Performant with intelligent DOM diffing
    DOM as a rendering engine
    Optimizing with shouldComponentUpdate
    Recommended Material

  Rethinking Best Practices
    https://www.youtube.com/watch?v=DgVS-zXgMTk&hd=1
    I recommend watching Pete Hunt’s Rethinking Best Practices if you watch or read
    nothing else. He talks a bit about React on a high level, but also focuses a
    lot on why they think the approaches they take are good ideas. Try not to let
    the giant fish tank distract you too much.

  Introduction to React
    https://www.youtube.com/watch?v=XxVg_s8xAms&hd=1
    This video is a bit older and has some duplicate content, but covers the idea
    of a uni-directional data flow in a tiny bit more detail, and explains what
    benefits this has over a more traditional MVC architecture in client-side
    applications.  Though the video length on YouTube is 1 hour 20 minutes, the
    main part of the talk is actually a bit under 30 minutes—there is a lot of Q&A.
    The diagram shown at ~3:30 will lead us into a discussion of the “Flux”
    architecture (maybe FB’s blog post on it will be out by the time we meet).

  Learning React
    """ The React site is pretty good; they have a decent tutorial you can follow if
    """ you wanna get some hands-on experience with React, and the rest of the docs are
    """ pretty solid. I found Thinking in React to be interesting and useful.

    Imgur Gallery Browser

    Imgsible
      It uses something similar to the Flux architecture with some changes. The readme has a bunch of notes.

Retrospective

* Tough to understand some of the FRP papers due to haskell/FP terminology.
  Revisit Push/Pull FRP after functor/applicative/monoid review in March

Writing ideas

• write comparison of: react/meteor/angular/ember runloop/coalesce/deps ?
  • maybe there are 2 difference concerns here; push/rx/deps and batching updates
  • that's a fair thing - i think some of the frameworks do both (angular, maybe meteor? idk the others)

Projects

• Meteor
  • toy meteor chat app
• React
  • toy viewport splitter
